3par port hosts

Hello There, This is more specific to HP 3par Inserver Storage product line. Just wanted to check to see if the host ports on the 3par have to be reservered for different platform OS. I mean can we mix ESX servers with other windows or linux hosts or does ESX have to be on thier own dedicated ports? If so why? Or any other OS has to be on thier own ports and cannot mix with others?
